Ubiquitous credit card brands MasterCard and Visa warned today of a security breach that could potentially impact up to 10 million card holders.
First reported by the blog Krebs on Security, MasterCard and Visa – the two biggest credit card issuers in the world – have been notifying banks today that a massive security breach happened at a third-party card processor that could potentially impact up to 10 million card holders. Apparently the breach happened between January 21, 2012 and February 25, 2012 and seems to be focused around cards that were used in New York City taxis.
Right now these are the only two card companies issuing the warnings, but other companies such as American Express, Bank of America and Discover are monitoring their customer’s account activity to see if anything unusual turns up.
The thing consumers can do right now is to make sure to check their bills for any activity that they don’t recognize, and remember that they are not responsible for any fraudulent charges.
